_Dysgrammatism_ (Kussmaul) _and Agrammatism_ (Steinthal).--Children can _not yet_ put words into correct grammatical form, decline, or conjugate. They like to use the indefinite noun-substantive and the infinitive, likewise to some extent the past participle. They prefer the weak inflection, ignore and confound the articles, conjunctions, auxiliaries, prepositions, and pronouns. In place of "I" they say their own names, also _tint_ (for "Kind"--child or "baby"). Instead of "Du, er, Sie" (thou, he, you), they use proper names, or man, papa, mamma. Sometimes, too, the adjectives are placed after the nouns, and the meaning of words is indicated by their position with reference to others, by the intonation, by looks and gestures. Agrammatism in child-language always appears in company with acataphasia, often also in insane persons. When the imbecile Tony says, "Tony flowers taken, attendant come, Tony whipped" (Tony Blumen genommen, Waerterin gekommen, Tony gehaut), she speaks exactly like a child (Kussmaul), without articles, pronouns, or auxiliary verbs, and, like the child, uses the weak inflection. The connection _m_ of the word-image-center W with the diction-center D, i. e., of the word-memory with grammar, and the centers themselves, are as yet very imperfectly developed, unused. _Bradyphasia._--Children that can already frame sentences take a surprising amount of time in speaking on account of the slowness of their diction. In D and W _m_ in the cerebral cortex the hindrances are still great because of too slight practice. (3) The Motor Processes centrally disturbed. _a. Centro-motor Dysphasia and Aphasia, Aphemia, Asymbolia, Asemia._--Children have not yet learned, or have hardly learned, the use of language, although their intelligence is already sufficient. There is no longer any deficiency in the development of the external organs of speech, no muscular weakness, no imperfection of the nervous structures that effect the articulation of the separate sounds, for intelligence shows itself in the child's actions; he forms the separate sounds correctly, unintentionally; his hearing is good and the sensory word-memory is present, since the child already obeys. His _not yet_ speaking at this period (commonly as late as the second year) must accordingly be essentially of centro-motor character. In the various forms of this condition there is injury or lack of sufficient relative development either in the centro-motorium M or in the paths that lead into it, _d_, _e_, _f_ as well as _i_, _l_, _n_. _[alpha]. Central Dysarthria and Anarthria._--In the child at the stage of development just indicated articulation is _not yet_ perfect, inasmuch as while he often unintentionally pronounces correctly sounds, syllables, and single words, yet he can not form these intentionally, although he hears and understands them aright. He makes use of gestures.
